BMPRO SwayControl Proactive Electronic Stability Control and Loom Proactive electronic stability control The BMPRO SwayControl system reduces caravan and trailer sway automatically, enhancing safety by correcting sway without driver input. It monitors trailer yaw and applies braking force independently to either side of the trailer brakes. Mounted under the caravan or trailer chassis, the unit connects to the trailer braking system. It detects sway caused by road conditions, wind, passing vehicles, driver errors, or uneven loading and applies brakes to stabilise the trailer. The system includes a prewired loom for simple installation. Features Independent braking: Applies brake force only to the side experiencing sway for precise control. Axle compatibility: Works with single, tandem, triple, and four-axle caravans and trailers. Off-road mode: Automatically disables on sustained rough terrain.
